“…For example, chemolithotrophic iron/sulphur oxidizers may contribute to weather pyritebearing rocks by lowering the pH even when present at low abundances in the microbial communities (Borin et al, 2010;Mapelli et al, 2011). Endolithic Cyanobacteria may also contribute to silica dissolution through alkalinization (Mapelli et al, 2012). Interestingly, a red surface patina can be observed on Miage debris, whose lithology shows general similarities with the one described by Borin et al (2010), but is less widespread on the Belevedere, whose debris has a slightly different lithology and a more acidic substrate (see Supplementary Information).…”

Bacterial community structure on two alpine debris-covered glaciers and biogeography of Polaromonas phylotypes

High-elevation cold environments are considered ideal places to test hypotheses about mechanisms of bacterial colonization and succession, and about bacterial biogeography. Debris-covered glaciers (glaciers whose ablation area is mainly covered by a continuous layer of rock debris fallen from the surrounding mountains) have never been investigated in this respect so far. We used the Illumina technology to analyse the V5 and V6 hypervariable regions of the bacterial 16S rRNA gene amplified from 38 samples collected in July and September 2009 at different distances from the terminus on two debris-covered glaciers (Miage and Belvedere-Italian Alps). Heterotrophic taxa-dominated communities and bacterial community structure changed according to ice ablation rate, organic carbon content of the debris and distance from the glacier terminus. Bacterial communities therefore change during downwards debris transport, and organic carbon of these recently exposed substrates is probably provided more by allochthonous deposition of organic matter than by primary production by autotrophic organisms. We also investigated whether phylotypes of the genus Polaromonas, which is ubiquitous in cold environments, do present a biogeographical distribution by analysing the sequences retrieved in this study together with others available in the literature. We found that the genetic distance among phylotypes increased with geographic distance; however, more focused analyses using discrete distance classes revealed that both sequences collected at sites o100 km and at sites 9400-13 500 km to each other were more similar than those collected at other distance classes. Evidences of biogeographic distribution of Polaromonas phylotypes were therefore contrasting.

“…Fungi can bore into the stone and produce extracellular enzymes and metabolites that cause chemical and physical damage (Warscheid and Braams, 2000). Bacteria-producing acids, for example, nitrifying bacteria dissolve calcareous stone, whereas other bacteria and fungi feed on paint or other coatings applied to protect the material (Vollertsen et al, 2008;Mapelli et al, 2012).…”

The dual role of microbes in corrosion

Corrosion is the result of a series of chemical, physical and (micro) biological processes leading to the deterioration of materials such as steel and stone. It is a world-wide problem with great societal and economic consequences. Current corrosion control strategies based on chemically produced products are under increasing pressure of stringent environmental regulations. Furthermore, they are rather inefficient. Therefore, there is an urgent need for environmentally friendly and sustainable corrosion control strategies. The mechanisms of microbially influenced corrosion and microbially influenced corrosion inhibition are not completely understood, because they cannot be linked to a single biochemical reaction or specific microbial species or groups. Corrosion is influenced by the complex processes of different microorganisms performing different electrochemical reactions and secreting proteins and metabolites that can have secondary effects. Information on the identity and role of microbial communities that are related to corrosion and corrosion inhibition in different materials and in different environments is scarce. As some microorganisms are able to both cause and inhibit corrosion, we pay particular interest to their potential role as corrosion-controlling agents. We show interesting interfaces in which scientists from different disciplines such as microbiology, engineering and art conservation can collaborate to find solutions to the problems caused by corrosion.

“…In 2016, Shi et al published a review in the Journal of Nature Review on microbes [6], which systematically summarized the mechanism of interaction between minerals and microbes, focusing on two basic sciences of energy and extracellular electron transfer. In addition, domestic and foreign scholars have studied the different systems and related mechanism of soil mineral-microbial interaction, involving the microbial adsorption process on the surface of minerals [7,8]; they also studied the relationship between mineral-microbial-soil contaminants.…”

Carbonate mineralization microbe is a microorganism capable of decomposing the substrate in the metabolic process to produce the carbonate, which then forms calcium carbonate with calcium ions. By taking advantage of this process, contaminative uranium tailings can transform to solid cement, where calcium carbonate plays the role of a binder. In this paper, we have studied the morphology of mineralized crystals by controlling the mineralization time and adding different concentrations of montmorillonite (MMT). At the same time, we also studied the effect of carbonate mineralized cementation uranium tailings by controlling the amount of MMT. The results showed that MMT can regulate the crystal morphology of calcium carbonate. What is more, MMT can balance the acidity and ions in the uranium tailings; it also can reduce the toxicity of uranium ions on microorganisms. In addition, MMT filling in the gap between the uranium tailings made the cement body more stable. When the amount of MMT is 6%, the maximum strength of the cement body reached 2.18 MPa, which increased by 47.66% compared with that the sample without MMT. Therefore, it is reasonable and feasible to use the MMT to regulate the biocalcium carbonate cemented uranium tailings.
